- 2The Malwa Plateau dominates the Vindhyan scarps, forming the Eastern flank of the plateau.
- 3The Western Satpuras separate the Narmada and Tapi rivers.
- 4The Chota Nagpur Plateau is composed of Archaean granite and gneiss rocks.
Select the correct answer using the code given below :
- A1, 2, 3 and 4
- B1, 3 and 4 only
- C2 and 4 only
- D1 and 3 only
Explanation
Statement 1 is true: the Deccan plateau's elevation generally increases from north to south — the Karnataka plateau stands higher than the Maharashtra plateau. Statement 2 is false: the Vindhyan scarps form the southern flank of the Malwa plateau; the Malwa plateau neither dominates the scarps nor forms the eastern flank of the plateau. Statement 3 is true: the western Satpuras lie in the rift valley between the Narmada and the Tapi, separating the two river valleys. Statement 4 is true: the Chota Nagpur plateau is composed of Archaean granite and gneiss rocks. Hence statements 1, 3 and 4 are correct.
